The invention relates to the technical field of a packaging paper box and discloses a multifunctional solar panel packaging paper box. The multifunctional solar panel packaging paper box comprises a packaging box, a box cover, a vertical bar, a pull ring, a sponge block and a transverse block; the packaging box is connected with the box cover; and the packaging box is connected with the vertical bar. The multifunctional solar panel packaging paper box realizes multiple functions; the sponge block on the inner side of the pull ring achieves the effect of protecting a palm, so that during manualcarrying, the palm and the pull ring are contacted more comfortably; in addition, the pull ring, the transverse block and the vertical bar achieve the effect of enhancing the local strength and the packaging box is not liable to damage in the carrying process; a waterproof layer is made of a polyethylene polypropylene fiber composite waterproof coiled material and can achieve a waterproof effect,so that damage to the solar panel caused by the fact that the packaging box is immersed into water is avoided; and the flame-retardant plate achieves a flame-retardant effect, so that accidental fireis avoided, the possibility of damage to the solar panel is reduced and the solar panel is protected better.
